Progress in the development of small molecule inhibitors of insulin-like growth factor-1 receptor kinase

Abstract

Insulin-like growth factor-1 receptor (IGF-1R) is a receptor tyrosine kinase that plays a key role in tumor cell proliferation and in the inhibition of apoptosis, and therefore is a potential target for the treatment of cancer. The blockade of IGF-1R kinase activity by small molecule binding to the catalytic domain of the receptor offers promise for the future and this review summarizes the patent literature from 2000 to early 2006.
